If you need to customize Firefox for any reason, whether it be deployment within your organization or a custom version for your family and friends, the CCK2 is the tool for you.

With the CCK2 Wizard, you can customize the homepage, set (and lock) preferences, set permissions, add certificates, install add-ons, install search engines, add bookmarks, set the default network configuration and more.

You even have the choice of creating an extension to deploy your changes or using AutoConfig, a powerful mechanism within Firefox for customizing Firefox before you deploy it.

The CCK2 is the best way to customize Firefox.
